Thanks for the comments.
With the options trading at $0.155, and the exercise price at $0.20, this represents a total cost of $0.355, which is similar to the current share price.
I'll probably wait to see the outcome of the situation in Europe before I buy any more shares.
One further question, if a takeover offer is made for AKI, then I assume the takeover making company is obligated to buy the options as well?
